J l l To all 'ze/mm. it mai concern lie it known trat I, WILLIAM H.Hanonxvn, a citizen of the United States, and a resident of Portland,county of Multnomah, and State of Oregon, have invented a new and usefulImprovements in Cable-Clamps, of which the following is a specification.

'lhis invention has for its object to provide a simply constructed andefhcient clamp for a cable, also to so construct the exterior of theclump as to facilitate its passage through a pulley-block.

My invention also has for its purpose t-o provide efficient andconvenient means for securely clamping the ends of a cable used fortying togetherl the ends of the logs in the boom sticks of a ra ft; andin connection with these purpos the further objects of my device is toso construct my clamp that all of the parts thereof may be convenientlycast, that it consists of only a few pieces, and that the parts thereofmay be interchanged.

These and incidental features are fully explained in the body of thespecification.

In the accompanying drawings: Figure 1 shows my invention as a plied inthe form through a loe, as in the construction of a log-raft, the Towerportion of my cable being shown in full outline and the upper portion insection; Fig. 2 is a pers ective of one of the interchangeable arts othat part of my box which I term t e longitudinally divided box; Fig. 3is a perspective outer cad view of one of the sleeve parts fitting overthe ends of the box parts when assembled on a cable; Fig. 4 1s asectional end view approximately taken on a line :v-w of Fig. 1 andlookin to the right; Fig. 5 shows the applieatlon of my invention forclamping the ends of a cable used for tying together the ends of a boomstick of a log raft, the lower portion of my clamp being shown as anexterior view and the upper portion in section; and Fig. 6 is aperspective of one of the interchangeable parts of the box constitutinga part of the type of my clamp illustrated in Fig. 5.

Describing in the first instance the type of my cable-clamp shown inFigs. 1 to 4 inclusive: a is what I term the lon 'tudinally divided box,eomprisin prefere l two parts each of the form iown in Fig. 2 and fformed with a lo itudinal recess b, of

larger cross-section t an the ends, c, c, so as Specification of LettersPatent.

to rovide room for receiving a filling of bab itt cast about the cableand securingit in the box against endwise movement. Each part of the boxis further formed with a central transverse flange d, provided withperforations, e, for receiving bolts. When the two parts of the sleevehave been assembled on the cable, and the babbitt filling has also beenintroduced, there is slipped over the ends of the box-portions sleevesf, g. each formed with companion flanges /L and provided withperforations 7', registering with the pcrforations, e, of the flanges dof the box parts, and the sleeves, f, g, are bolted to the flange d ofthe box parts by bolts and nuts j.

The type of clamp shown by me in Fig. 1 is such as would be serviceableas a collar, and it is frequently convenient to have the clamp soarranged as to readily pass through a pulley-block. To accomplish thispurpose, the sleeves are formed with longitudlnal radial webs 7c.

Z in Fig. 1 represents the babbitt filling cast on the cable m, and nrepresents a log having a hole bored at one end throngli which the cablem is inserted.

The t-ype of my clamp illustrated in Fig. is such as is serviceable forsecuring the ends of a cable used in tying together the ends of the logsin the boom stick of a raft. The log ends are represented by o, o',having holes bored at through which the ends g, q', q of the cab e loopsr, 1" are inserted, said cable ends being fastened together by my clamp,as shown. In this instance my clamp comprises u longitudinally dividedbox s, preferably made in two parts, each of the form shown in Fig. 6,and formed with n. plurality of longitudinal recesses t, of larger crosssection than the grooves t', for receiving the cable, so that a babbittfilling may be cast about the cable in said recess t to secure the cableagainst endwise movement. Each of the box parts is further formed with acentral transverse flange il, having perforutions u for receiving bolts.Slipped over the ends of the assembled box parts are sleeves o, w, madewith companion flanges v', w', respectively, which are bolted to theflange u of t-he box parts by means of bolts and nuts y.

It will be noted that my clamp is adapted for different sizes of cab es,by making my clamp of the size fitting the cable of greatest diameter;and by making the type of clamp illustrated 'in Fig.. 5, .the ends ofcables of different diameter ma be clamped together in the manner aboveescribed.

In the operation of securing cable ends by myclamp, the cable ends aretemporarily secured'in place by any convenient means, so as to liewithin the box parts, and the sleeves are then put in place, the clampbeing held meanwhile, by some convenient means, in upright position sothat the babbitt may bo poured into the core of the box tho bottomopenin of the core being close by holding `a .clot against the sameuntil the babbitt has solidified. If the cable ends are later to beseparated, the sleeve parts are first removed, then the box arts, afterwhich the babbitt can be rcadi y removed mechanically or by meltingofi'.

I claim:

1. A cable clamp consisting of a longitudinally divided box the parts ofwhich are interchangeable, each part beingJ made with a core recess forreceivin a ca le, said recess being adapted to ho d a metal filling castin it about the cable; each of said box parts being formed with acentral transverse flange, sleeve ends adapted to be placed on theopposite ends of the assembled box parts; each sleeve being formed witha companion flange at its inner end; and means for securing the partstogether.

2. A cable clamp consisting of a longitudinally divided box the parts ofwhich are interchangeable, each part being made with a core recess forreceivin a cable, said recess being adapted to ho d a metal filling castin it about the cable; each of said box parts being formed with acentral transverse flange, sleeve ends adapted to bc Elaced on theopposite ends of the assemled box parts; each sleeve being formed with acompanion fixings at its inner end and with radial peripheral webs,tapering longitudinally from said flange to the e.\'t.rein1t \v of thesleeve end; and the flanges of the parts bein provided with registeringperforations 01` receiving bolts, the perforations of the sleeve flangesbeing located intermediate said webs, tlie latter constituting a partialhousing therefor.
